5 calms. (c1. zo-sas) My invention relates to new and useful improvements in a window glass insulation system,. and has for one of its objects to apply one or more additional panes of glass to a window sash or door torprovide a dead air space or spaces which will act as insulation against a temperature on the outside of a building different from the temperature on the inside ofthe building.

Another object of my invention is to provide means for assembling one or more additional panes of glass on a stock. door or window sash or ones that are now in use.

Another objectof the present invention is to installone or more additional panes of glass on a window sash or door in a manner to make the joints about the additional paneor panes air tight.

A further object ofthe invention is to provide moulding for installing the additional pane-or panes of glass, which moulding is grooved or chambered to receive an'd hold a suitable plastic composition to function as caullnngmeans.

A still further object of m'y invention is the provision of a window glass insulation system applicable to new, stock and used doors 4and window sashes wherein one -or more additional panes of glass are held in place by moulding attached to one or both faces of a doorA or window by one or more dead air spaces are produced which function asheat insulation, said moulding carrying aplastic compound to caulk the joints and prevent leakage of air into and from the dead air spaces.

' Still another object of the invention is -to provide vfor sealing the joints of certain types of the regular panes of glass in doors or windows whenever it is necessary.

With the above and othercbjects in view, this invention consists of the details of construction and combination of elements hereinafter set forth and then speciiically designated by the claims.

In order that those skilled in the art to which this invention appertainsmay understand -how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawing forming a part of the application, in which;

Fig. l is a fragmentary broken view of a window sash illustrating one application of my invention.

Fig. 2 is'a horizontalsectional vriew of Fig. l.

Fig. 3 is a vertical section in the region of the meeting rails of two equipped .with that form of the invention illustrated in Figs. i and 2.

Fig. 4 is a view similar to Fig. 3, showing'a modiiied form of moulding.

' Fig. 5 is a sectional viewillustiating the use two additional panes of glass and showing one of them inset for use in connection with double hung or sliding sashes, and

Fig. 6 is also a sectional view illustrating th use of two additional panes of glass, both on the faces of the sash and showing an alternate f orm 5 of moulding.

In carrying out my invention, l0 represents a frame included as a part of a door, window sash or the like, which is .usually rabbeted, as at II to receive the regular or primary pane of" glass i2, 19 held in place by suitable means I3, such as putty or moulding. In some instances one edge of the pane of'glass I2 is merely set in a channel i4, Figs. 3 and 4 and often no sealing means is used.

By referring particularly tongs. 1, 2 and 3,1: 1 will be noted that an additional or secondary pane of glass I5 is placed directly against the face of the frame I0 so as tov be disposed across the light opening and in-spa'ced parallel relation to the primary pane of glass I2. Where Athe invention is used in connection with double hung held in place by moulding I6 which, in the pargroove orchamber 20 for the reception of a plastic composition 2|, such as caulking compound, 30.

that seals the joint between the secondary pane of glass and the frame I3 and Aprevents leakage of air around said secondary pane.

By this arrangement of the two panes of glass, a dead `aixspace 22 is formed that efciently in- 40 sulates one side of the frame from the other and 'prevents the passage of heat or cold, as they case may be, from the outside to the inside of a building. It also prevents the accumulation of moisture due to condensation and the resultant frost 45 In the application of my invention, whenever a sash is encountered in which the usual or primary pane of glass isinstalled by having one edge inserted in a channel, as shown in connection with the lower sash at I4 in Fig. 3, such lpane 6 of glass is sealed by a sealing moulding ll. This moulding is similar to that previously described except that the lip is about a quarter of a circle instead of approximately a semicircle. The sealing moulding also holds a plastic composition 35. I have illustrated the same invention in Fig. 4 to show the use of moulding produced from wood and therefore wherever identical parts are used they will be referred to by the same references numerals as previously employed. The mouldings are interchangeable and all metal or all wood or some metal and some wood ones ycan be used. on the same installation.

As previously stated the secondary pane of glass i5 is placed against a face oli the frame l0 and as shown in Fig. 4, moulding 24 produced from .asti-ip of wood having any'suitable or desirable conilguration, is used to secure thesecondary pane in position.

. groove or chamber to hold the plastic composition 28 for sealing the joint between the secondary pane and the frame. In addition to the groove or chamber in the lip, one or more longitudinal A grooves or chambers 29 may be produced in the inner face of the flange to hold plastic composition to further insure an air tight seal about the secondary pane of glass.

In the same manner as before outlined, the combination of the secondary pane with the primary pane produces the. dead air space 22.

The reference numeral 30 indicates a sealing moulding for use in the same manner as the'one shown at 34 in Fig. 3, but in this instance it is produced from a strip of wood with a longitudinal groove orchamber to hold the plastic composition 2| for making the primary pane air tight. In Fig. 5, I have illustrated the same invention carried out to provide two dead air spaces 22a and 22h, and in this modification the primary pane of glass is installed in the usual or ordinary manner, then the secondary panes of glass I5 and lia are assembled on the frame so that one secondary pane is on one side of the primary pane and the other secondary pane is on the opposite side of said primary pane.

- One of the secondary panes, as I5, is mounted in the manner hereinbeiore described and the other can be mounted in the same manner, as

suggested by the showing in Fig. 6,'to be later described, but when used in connection withdouble hung sashes one of the secondary panes. must be inlet sufilciently. to eliminate any projections-beyond one faceof the sash. For this purpose the secondary pane I5a is shown as set in a rabbet 32 and held in place by glazing'means a 33, such as plain moulding, moulding holding the plastic composition as above described, putty or any equivalents. i

As illustrated in Fig. 6, the two dead air spaces 22a and 22h are produced by the use o! two secondary panes of glass I5 and lia held in place on opposite faces o! the frame. I0 by moulding strips y 2l, which as illustrated are the same as Siown inVFlg. 4,1311; since the :mouldings VIl and 2| are interesan table,A it will be Aobvious that .the moulding." can be used instead of the one shown.

' vention is applicable to present day windows and an air tight joint between This adaptation of the invention is particularly useful in connection with doors, casement windows or ilxed frames.

From the foregoingvit will be understood that I have provided a simple and inexpensive systemor structural arrangement that makes it possible to readily insulate windows, doors and kindred objects without the necessity of manufacturing specially designed frames, so that the-indoors which are or have been in use as well as stock frames.

Of course I do not wish to be'limited to the exact details of construction herein shown and described, as these may be varied within the scope of the .appended claims without departing from I the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is;-

l. A frame having a primary pane of glass therein, a secondary pane of glass placed against one face of said frame in spaced parallel relation to the primary pane to form a dead air space, a Ichambered moulding secured to the frame and overlapping the margins of the secondary pane, and a plastic composition in the chamber o! the moulding to' make an air tight joint between the secondarypane and the frame.

2. A frame having a primary pane of glass therein, a secondary pane of glass lying against 30 a face of said frame in spaced parallel relation to the primary pane to form a dead air space, a

moulding including a angeby which said moulding is secured to the frame and a lip overlapping the margins of said secondary pane to hold the latter in place and said lip having a longitudinal groovev orV chamber in its inner face, and a. plas tic composition in the chamber to seal and make the frame and the secondary pane.

3. The structure in-claim 2, wherein the ange oi the mouldingalso has one or more longitudinal grooves or chambers in its inner face for the reception and retention of the plastic composition.

4. The combination with a window frame having a primary pane ot. glass therein, of means to `maire the joint between the frame and said pri--l mary pane of glass airtight, said means being independent of th'e means ordinarily used for hold- 50 ing the glass in place, a secondary pane of glass placed against one face o! said frame in spacedI parallel relation to the primary pane to form 'a dead air space, a chambered moulding secured to the frame and overlapping the margins of the 55 ing a primary pane of glass thereima chambered vmoulding secured to the frame andcontacting a face of thel glass, a plastic composition in the chamber offsaid moulding to make an airtight joint independently of the means ordinarily used for holding the primary pane of glass in place,

a secondary pane of glass placed against one face of said frame in spaced parallel relation to the primary pane to iorm a dead air space, a chambered moulding secured tothe frame and overlapping the margins of the secondary pane, and '70'.

a plastic composition Ain the chamber of fthe moulding to make an air tight Joint between secondary pane and the frame.
